I've had this little bugger kicking around for a long while. The one pictured is the 10 watt version, but I have the 50 watt. It's a pretty slick little amp but haven't been able to find much info about it.
I don't know if other amps have this capability, but on this little monster I can turn down the gain and volume and run a purely reverb signal that sounds like a mad whale locked in a concert hall with a cardoid helmet strapped to its head. I love it for when we have our improv noise sessions.
